IMPROVEMENT IN BAG-FASTENERS.

Specification forming part of Letters Patent No 209,233, dated October22, 1878 application filed May 17, 1818.

To all whom it may concern:

Be it known that I, EDWARD W. 00X, of Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Bag-Fasteners, of

which the following is a specification:

My invention relates to bag-fasteners for clamping or tying the mouthsof bags.

It consists in passing both ends of the bindingstring through a slidin gscrew-clamp arranged to receive and retain them, and at the pleasure ofthe operator be free to slide upon the said string, to admit of theopening and closing of the bag, or be clamped tightly thereto to keepthe bag closed. In the accompanying drawings, Figure 1 is a perspectiveview of a bag with my device attached theretor Fig. 2 is a perspectiveView of my fastener, and Fig. 3 a longitudinal section of the same.

Letters of like character represent corresponding parts in each of thefigures.

The ends a a of the string are passed through the clamp A between thepieces I) 0, one on each side of the screw 0. When the clamp is open thestring is retained therein by the notches d d. The part c, I prefer toform of an approximately-semi-cylindrical shape, with the lips orflanges c projecting from its sides, as shown, and in these lips are cutthe said notches d d. Thepart b is simply a bar of about equal lengthwith the part c, and fitting between the lips or flanges-c. The part chas through its center a screw-threaded hole, and the part I) has asmooth round hole, which coincides with this screw-threaded. hole whenthe two parts are placed together. 0 indicates a screw, having theshoulder e projecting laterally from its head. The screw 0, being passedthrough the two parts I) and c, engages with the threaded hole of thepart c, and when said screw is turned to the right the travel of thescrew draws the shoulder 6 against the part b, so

that the cords passing through the notches d d are clamped between saidparts In and c.

The operation of this device may be briefly described as follows: Theends a a, of the string are passed through the notches d d, then tiedtogether, so as to prevent the clamp from falling off when loose uponthe string. To close the bag the clamp A is pushed against the bag withone hand, while with the other the string a a is pulled through it untilthe bag is closed. Then the screw 0 is turned and the clamp A holds thebag securely closed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A bag-fastener consisting of the pieces I) 0, arranged one within acavity of the other, and the outer one having the two notches d d in itsedge for receiving the two ends of a string, in combination with theset-screw e,

passing through both said pieces 21 c, for clamp-' ing them together, asand for the purpose described.

In testimony whereof I .have hereunto set my hand this 9th day of May,1878.
